Specification of Letters Patent.

Application mea my 2a, 191s. serial no. 770,653.

T 0 all whom t may concern."

Be it known that I, VJACOB H. GENTER, a citizen of the United States,and a resident of Newburgh, in the county 'of Orange and State of NewYork, have invented a new and Improved Apparatus l for Agitatingl\[atcrials, of which the following is a full, clear, and exactdescription.

The objectl of the'invention is to provide a new and improved apparatus,more especially designed foruse in households as a Hour sifter, doughmixer, eg beater, ice cream freezer and the like, an arranged to allowconvenient and quick interchange of the parts topermit using theapparatus for the various purposes.

Inorder to accomplish the desired result, use is made of a stationaryvessel provided with a central tube open at both ends, a vertical sha-ftextending through the `said tube and receiving at its upper endremovable agitating devices of various kinds, and a driving gearconnected with the lower end of the said vertical shaft, to rotate thelatter and the agitating devices.

A practical embodiment of the invention is represented intheaccompanying drawings forming a part of this specication, in whichsimilar characters lof reference indicate corresponding parts in all theviews.

Figure l is a sectionalside elevation of the apparatus arranged as aflour sifter; Fig. 2 is a side elevation of the device for locking thecover in place on the upper end of the vessel; Fig. 3 is a sideelevation of the stirrer for` mixing dough and the like; Fig. 4 is asectional side elevation of a modified forni of the apparatus arrangedas an ice cream freezer; 5 is a sectional plan view of the means forfastening the sieve and cover in position on the vessel; and Fig. 6 isan enlarged sectional Side elevation of the bearing for lthe lower endof the vertical shaft.

On a table A is removablysecured, by a set screw B', a support B, onwhich is fastened a vessel C adapted to be closedv at the top b v acover D, having a' filling opening D', covered by a door or slide E, andserv- 'ing for placing materials in the vessel C, as

hereinafter more fully explained. In the vessel C rises centrally a tubeF, through which extends a vertical shaft Gr, provided at its lower endwith a bevel gear wheel H, l in mesh with a bevel gear wheel H',attached to a horizontally yextending shaft I, journaled in the supportB, and carrying at one outer end a crank arm J underr the control of theoperator for turning vthe driving shaft I, to rotate the vertical shaftG. The lower end of the shaft G is mounted on a bearing K, screwed orvotherwise secured in the .support B, and the upper reduced end G ofPatented Jan. 18, 1916. l

removably secured to the inside of the upper end of the vessel C. Nowwhen the shaft G is rotated, the agitator L sweeps over the sieve N, soas to sift the flour or vother material placed in the sieve, asindicated in Fig. l. As shown in the drawing, the sieve N is sphericaland the arms ofthe agitator L are segmental, to it the inner surface ofthe sieve \T. By the arrangement described, flour or like materialplaced in the sieve is sifted into the lower portion of the vessel C.When the desired amount of fioul' has been sifted into the vessel C, thecover D is removed and likewise the agitator L and the sieve N, and thenanother agitator 0, such as shown, for instance, in Fig. 3, is placed inposition on the upper end of the shaft-Gr,l

to stir the ilour and with it the water, milk or other ingredientsplaced inthe vessel C. The agitator O isvprovided with a hub O2, havinga polygonal recess`0, fitting the polygonal portion Gr2 of the shaft G,so that when thelatter is rotated the agitator is carried around withthe shaft. From the hub O2 extend agitatingarms O3, O, which come incontact with the flour or other ingredients, to stir the same with aview to form dough and to mix and knead the dough.

By reference to Figs. 1 and 3, it will be noticed that the large portionof the hub O2 extends over the end of the fixed tube F, so that the'materials contained in the-vessel C or the sieve N, are not liable towork into the tube F and to the gearing, to clog the same. It will alsobe noticed that the shaft G is wholly independent of' the tube F, as thelower end .of the shaft is j ournaled on the support B and the upper endof the cover D, which is replaced every time after the agitatingdeviceshave beeninterchanged.

55 vessel Q in unison with the agitators P. From the foregoing, it willbe seen thatand the sieve N in position on the vessel C.

It is understood that forvarious household purposes differently shapedagitator-s are provided so as to permit of conveniently usingthe devicefor churning .cream and the like, for beating eggs, for whipping cream,etc.

When using the apparatus as an ice cream freezer, the construction shownin Fig. 4: is preferred, and in this case the support B3 is secured tothe table A', and in it is joui-- naled a driving shaft I provided atits outer end with a crank arm J', and at its inner end with a bevelgear wheel H2, in mesh on op osite sides with bevel ear wheels H3, I 4.The bevel gear wheel 3 is secured to the lower end ofthe vertical shaftG, extendingrupward through the tube F3, fixed in the vessel C attachedto the support B3, and mounted on a bearing K screwed or otherwisesecured in the support B. To the upper end of the shaft G are securedagitating devices P, extending within a vessel Q, arranged within theVessel C', so that ice or other freezing medium can be packed betweenthe vessels C and Q. The bevel gear wheel H* previously mentioned, issecured to the lower end ofa hollow shaft R extending through the tubeF3, and through which extends the shaft G, and on the upper end of thishollow shaft R arel secured agitating devices S, extending into thevessel Q, to co-act with the agitating devices P. Now when the operatorturns the crank arm J the shaft I is rotated, and the rotary motion ofthe latter is transmitted by the gear wheels H2, H8 and H4 to the shaftsGrS and R, to rotate the said shafts Gr3 and R in op-` positedirections, to insure turnin of the agitators AP and S in oppositeirections within the vessel Q.

If desired, the vessel Q may be attached to the upper end of the shaftG8, to rotate this the'agitating devices are driven by means extendingfrom thebottom of the vessel C, up through `the center thereof, and exitof the material contained in the vessel is prevented by the fixed tubeF, through which extend the vertical portions of the driving means forthe agitators. It will also be I noticed that by the arrangementdesdribed, a quick interchange of agitators can he made so as to enablea person to utilize the device for various purposes, as described.

In order to prevent leakage of the contents of theinner receptacle Q,the latter is provided with a central tube Q, through which extends thefixed tube F3,'as shown in Fig. 4. Y

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. An apparatus ofthe class described, comprising a support providedwith means for detachably securing it to a table, a Vessel mounted onthe support and having an open ended central tube extending to within ashort distance of the top of the Vessel, a perforated receptaclesupported in the vessel above the bttom'thereof, a vertical shaft havingits lower end mounted in the support, said shaft extending through thetube of the Ivessel and having a polygonal portion adjacent its upperend and above the tube, a stirrer provided with an elongated hub havingarms at its lower end shaped to fit the receptacle and a longitudi- 9onal bore, said hub fitting upon the tube and receiving the polygonalportion of the shaft. with the end of the shaft projecting through thehub, a removable .cover having on its inner face a central projectionengaging the hub and in which the upper end of the shaft is mounted, ahorizontal shaft mounted in the support and having a crank at itsouterend, and gearing between the horizontal and vertical shafts. l v

2. In a device of the class described, a support provided with lugs, avessel mounted upon the support and provided with a central open endedtube, the tube having an inverted cup-shaped lower end and provided onits inner face with lugs between which and the wall of the cup-shapedend the lugs of the support project, a cover for the vessel, a verticalshaft extending through the tube and journaled in the sup- 110 port andcover, a gear wheel on the shaft f within the cup-shapedend of the tube,a stirrer secured upon the upper end of the shaft below the cover, andahorizontal shaft mounted inthe support and having at its inner end` agear wheel meshing with the gear Wheel of the vertical shaft.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
